Entropy also increases in initially ordered quantum systems until it reaches a final state of disorder. Entropy and the direction of time Equating 'entropy' with 'disorder' is not entirely correct.

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

Entropy gets a bad rap. Typically associated with randomness and chaos, it can also correlate with freedom and diversity. Cornell researchers have found that, thanks to the latter qualities, entropy ...

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...
